MAC HINE FOR WINDING WIRE-SOLDER.

SPECIFICATION forming part Of Letters Patent N0. 547,231, dated October1, 1895.

Application filed May 2, 1895. Serial No- 4'718 1- (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK W SCHULTZ, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Machines for Winding Wire- Solder, ofwhich the following is a specification.

This invention relates to a machine for winding wire-solder on spools.

The construction of the machine will first be described, and theinvention then pointed out in the claim.

The invention is illustrated intheaccompanying drawings, in which Figure1 is a front elevation of the machine. Fig. 2 is a side elevationlooking from the right side of Fig. 1 toward the left with thedrive-pulleys, however, removed. Fig. 3 is a view of the oscillatoryframe which carries the two gears. Fig. at is a sectional view of thewire-solder guide and the tension device. Fig. 5 is a detail sectionalview of the guide.

The machine is mounted on a suitable stand A. The spool B, on which thewire-solder is to be wound, is supported in a suitable chuck c c, whichadmits of readily removing a filled spool and inserting an empty one.The chuck part c is fixed on the end of a revoluble shaft D, whichcarries the fast and loose pulleys E E, while the other part c of thechuck is adjustable in the well-known way. A belt F to communicate powerfrom a suitable source is shifted by means of a lever F to either one ofthe pulleys E E, so as to start or stop the revolution of the shaft. Theshaft D is supported bya yoke-shaped standard G and carries a pinion71.. A shaft I has its ends in bearings j and. revolves therein. Betweenthese bearings the shaft is screw-threaded, as atl. This screw-shaftcarries a pinion '5. An oscillatory frame It is triangular in shape andat one angle has an attached sleeve Each of the other two angles carriesa stud-pin Z, and on each pin are mounted pinions m m, which engage eachother. The pinion h on the main shaftD may engage either of the twopinions m or m, according as the oscillatory frame is tilted one way orthe other. The pinion m remains in constant engagement with the pinionc'on the screw-shaft. The sleeve lo fits loosely on the end of thescrew-shaft I, which arrangement serves as a pivot, and thereby theframe 7c may tilt or os= cillate, so as to engage either the pinion m orthe pinion m with the pinion h on the main shaft. It will then be seenthat the screwshaft I may be revolved in either direction, according asto which pinion m or m is engaged with the main pinion h.

The sleeve it fits in a bearing n, and a handlever 0 is attached to thesaid sleeve. This lever when moved tilts the oscillatory frame is andcauses the screw-shaft I to reverse its direction of revolution.

The wire-solder p to be Wound on the spool B ordinarily lies looselycoiled, as at p, on the floor as it comes from the machine whichproduces it. I provide a guide and tension device through which thewire-solder from this loose coil passes on its way to the spool. Ahorizontal bar (1 extends parallel with the sorewshaft I, in whichposition it is retained. A hub or nut T, which is internallyscrewthreaded, tits on the screw-shaft I. This hub has a double arm ortwo parallel arms .9 projecting forward, and in the space between thearms are two grooved tension-rollers t t. Between the first roller t andthe screw-threaded hub 'r is a funnel-shaped guide to. The Wiresolder ppasses upward through the funnelguide u, then over the first roller 15,then downward and under the second roller t, then up to the spool B. Itwill be understood that the revolution of the screw-shaft I will imparta horizontal movement to the hub or nut r and the guide and tensiondevice both forward and backward, according to the direction in whichthe screw may be revolving. The extent of this horizontal movementrelative to each revolution of the screw-shaft depends, of course, onthe number of threads to the inch on the said screw-shaft. It; will beobserved that the several gears h m m t connecting the main shaft (whichcarries the spool B) and the screw-shaft I (which carries the guide andtension devices) are exactly the same size, and that consequently witheach revolution of the spool 13 there is exactly one revolution of thescrew-shaft. Therefore, if the solder- Wire to be wound on the spool isone-tenth wire-gage a shaft I should be employed which hastenscrew-threads to the inch, and thereby at each revolution of thewire-spool the guide and tension devices will move a distance exactlyequal to the thickness or size of the wire. For different sizes of wiredifferent screw-shafts must be employed.

In order to afford support to the arms .9 and guide and tension devicesand to give them steadiness as they move backward and forward, atrear-projecting arm 8' extends over the bar q, and another arm 8 extendsbelow said bar. These two short arms 8 s slide along the bar q as therevolution of the screwshaft moves said arms.

The operation will be understood from the above description. The spoolcontinues to revolve and the solder-wire is wound thereon in layers.WVhen in winding in one direction that layer is complete, the operatortilts the oscillatory frame 70, which reverses the screw shaft I andcauses the guide and tension devices to move in the opposite directionand thereby winds another layer, and so on until the spool is full.

Having thus described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is-

The combination of a stand; a driving shaft mounted thereon; a windingspool; a chuck revoluble with said shaft and carrying the winding spool;stationary bearings on said stand; a screw-shaft, I, parallel with thesaid driving shaft and revoluble in said stationary bearings; astationary bar, q, extending parallel with the screw shaft; a hub or nutinternally screw-threaded and fitted on the said screw-shaft andprovided with a projecting arm; tension rollers carried by said arm; afunnel guide also carried on the arm and between said rollers and thescrew-threaded hub; and two arms, 5, 5 on the said hub or nut one ofwhich takes above and the other below said stationary bar and whichslide along the same, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.

FREDERICK W. SCHULTZ.
